RADlATOR CONNEGTION.

SPECIFICATION forming part of Letters Patent No. 376,481, dated January 17,1888.

Application filed March 30, 1887.

To all whom it m my concern-.-

Be it known that I, G'EoReE A. KILEY, a citizen of the United States, residing at Rochester, in the county of Mon roe and State of New York, haveinvented certain new and useful Improvements in Radiator-Connections; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to make asecure and reliable connection between radiator-sections at the upper end, so that they may be quickly taken apart or put together.

Figure 1 of the drawings is a front elevation partly in section; Fig. 2, a vertical section in detail and on an enlarged scale; Figs. 3 and 4, plan views of the nut and radiator-connection.

In the drawings, A represents the several sections which make up the radiator, through which hot air, steam, or water are made to circulate for heating purposes.

E and F are respectively the inlet and out let for the heat-vehicle in the hollow base A while the inner chamber, A, of each section communicates with the base-chamber.

Above the sections is arranged the top A or one of any preferred form.

What is thus far described is well known to the public and forms no part of my invention, which really consists inthe particular means by which I connect the radiator sections at their upper ends.

In one of the sections which is put on last I use the tapering threaded plug D in the screwthreaded aperture or, whose hole is sufficiently large to permit a convex nut, O, to pass through it and be screwed on the end of the hollow screw b and into the countersink or concavity a". This nut G is screwed home, so as to slightly mash the thread, and thus effectually prevent it from turning. This will yield to the force exerted on the wrench in removing the nut, and the threads of nut and screw will again run in their respective grooves.

B represents my hollow radiator-connection, which consists of two hollow integral drawings, the tapering screw bis worked into its corresponding screw-threaded aperture, a, of one section and the smaller screw, 12, through the.eorresponding screw-threaded aperture, a, of the next section. The convex nut O is then passed through the section-nut a and turned onthe end of the small screw b by a wrench having points which fit into the notches c. The connections are thus successively applied until the last one is in place, when a plug, D, is screwed into the screwthreaded aperture a.

It will thus be seen that the sections of the radiator have all been brought into full communication, firmly bound together, and yet so connected that they may be easily taken apart. Having thus described all that is necessary to a full understanding of my invention, what I claim as new, and desire to protect by Letters Patent, is

In radiators or other devices made in sections for the circulationof fluids, the two integral screws 1) b of difit'ering diameters and the convex nut G, in combiuation'wit-h radiator- V sections having the opposite screw-threaded aperture a a to receive said screws, as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
